SENDMAIL RELEASE 8
This directory has the latest sendmail software from Berkeley. See
doc/changes/changes.me for a summary of changes since 5.67.
Report any bugs to sendmail-bugs@sendmail.ORG
There is a web site at http://WWW.Sendmail.ORG -- see that site for
the latest updates.
******************************************************************
** DO NOT USE MAKE to compile sendmail. Instead, cd src and **
** use the "makesendmail" shell script. On many environments **
** this will do everything for you, no fuss, no muss. See **
** src/READ_ME for more details of compilation. See cf/README **
** for details about building a runtime configuration file. **

| MANUAL PAGES |
+--------------+
The sendmail manual pages use contemporary Berkeley troff macros. If
your system does not process these manual pages, you can pick up the
new macros in a BSD Net/2 FTP site (e.g. on FTP.UU.NET, the files
/systems/unix/bsd-sources/share/tmac/me/strip.sed and
/systems/unix/bsd-sources/share/tmac/*).
The strip.sed file is only used in installation.
After installation, edit tmac.doc and tmac.andoc to reflect the
installation path of the tmac files. Those files contain pointers to
/usr/share/tmac/, and those pointers are not changed by the `make
install` process. There's also a bug in those files -- make the
following patch:
*** tmac.an~ Tue Jul 12 14:29:09 1994
--- tmac.an Fri Jul 15 13:17:54 1994
***************
*** 50,55 ****

.rn TH xX
.so /usr/share/lib/tmac/tmac.an.old

--- 50,55 ----

! .TH "\\$1" "\\$2" "\\$3" "\\$4" "\\$5" "\\$6" "\\$7" "\\$8"
.rm xX
..
Rename the existing tmac.an to be tmac.an.old, and rename tmac.andoc
to be tmac.an.
tmac.an will choose between tmac.an.old, your old macros, or tmac.doc,
which are the new macros, so that both the new man pages and the
existing man pages will be translated properly.
I'm also told that the groff distribution from MIT has a tmac.doc
macro set that is compatible with these macros.

There are some things that may behave somewhat differently.
For example, the rules governing when :include: files will
be read have been tightened up for security reasons.

There are several related RFCs that you may wish to read -- they are
available via anonymous FTP to several sites, including nic.ddn.mil
(directory rfc), ftp.nisc.sri.com (rfc), nis.nsf.net (RFC),
nisc.jvnc.net (rfc), venera.isi.edu (in-notes), and wuarchive.wustl.edu

Put "send rfcNNN" in message body
nis-info@nis.nsf.net
Put "send RFCnnn.TXT-1" in message body
sendrfc@jvnc.net
Put "RFCnnn" as Subject: line

Warning to AIX users: this version of sendmail does not implement
MB, MR, or MG DNS resource records, as defined (as experiments) in
RFC1035.
+-------------------+
| DATABASE ROUTINES |
+-------------------+
IF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE: **** DO NOT ****
use the version that was on the Net2 tape -- it has a number of
nefarious bugs that were bad enough when I got them; you shouldn't have
to go through the same thing. Instead, get a new version via the web at
http://www.sleepycat.com/packages/db.1.85.tar.gz. This software is
highly recommended; it gets rid of several stupid limits, it's much
faster, and the interface is nicer to animals and plants. You will
also probably find that you have to add -I/where/you/put/db/include
to the sendmail makefile to get db.h to work properly.
Be sure you remove ndbm.h and ndbm.o from the db distribution. These
will cause problems with sendmail because sendmail already understands
about NEWDB and NDBM coexisting.
+--------------------+
| HOST NAME SERVICES |
+--------------------+
If you are using NIS or /etc/hosts, it is critical that you
list the long (fully qualified) name somewhere (preferably first) in
the /etc/hosts file used to build the NIS database. For example, the
line should read
128.32.149.68 mastodon.CS.Berkeley.EDU mastodon
**** NOT ****
128.32.149.68 mastodon
If you do not include the long name, sendmail will complain loudly
about ``unable to qualify my own domain name (mastodon) -- using
short name'' and conclude that your canonical name is the short
version and use that in messages. The name "mastodon" doesn't mean
much outside of Berkeley, and so this creates incorrect and unreplyable
messages.
+-------------+
| USE WITH MH |
+-------------+
This version of sendmail notices and reports certain kinds of SMTP
protocol violations that were ignored by older versions. If you
are running MH you may wish to install the patch in contrib/mh.patch
that will prevent these warning reports. This patch also works
with the old version of sendmail, so it's safe to go ahead and
install it.
+----------------+
| USE WITH IDENT |
+----------------+
Sendmail 8 supports the IDENT protocol, as defined by RFC 1413.
No ident server is included with this distribution. I have found
copies available on:
ftp.lysator.liu.se /pub/ident/servers
romulus.ucs.uoknor.edu /networking/ident/servers
ftp.cyf-kr.edu.pl /agh/uciagh/network/ident
If you want to run an IDENT server, I suggest getting a copy from
one of those sites. Versions are available for several different
systems, including Apollo, BSD, NeXT, AIX, TOPS20, and VMS.
+-----------+
| MAKEFILES |
+-----------+
The Makefiles in this release use the new Berkeley "make" that is
available in BSD Net/2 and 4.4BSD. If you are using this version
of make, you may notice one or two places where the Makefile includes
"../../Makefile.inc". This file is not included with the sendmail
distribution because it's not part of sendmail. However, it is,
in toto:
# @(#)Makefile.inc 8.1 (Berkeley) 6/6/93
BINDIR?= /usr/sbin
The other directories should all have Makefile.dist files that work
on the old make, albeit without all the niceties included.
You can also get a new Berkeley make from the Net2 release (available
on many public FTP archives). This version should also interpret old
Makefiles, so you could drop it in as your default make.
For more details, see src/READ_ME.
+-----------------------+
| DIRECTORY PERMISSIONS |
+-----------------------+
Sendmail often gets blamed for many problems that are actually the
result of other problems, such as overly permissive modes on directories.
For this reason, sendmail checks the modes on system directories and
files to determine if they have been trusted. For sendmail to run
without complaining, you MUST execute the following command:
chmod go-w / /etc /usr /var /var/spool /var/spool/mqueue
You will probably have to tweak this for your environment (for example,
some systems put the spool directory into /usr/spool instead of
/var/spool). As a general rule, after you have compiled sendmail,
run the command
sendmail -v -bi
to initialize the alias database. If it gives messages such as
WARNING: writable directory /etc
WARNING: writable directory /usr/spool/mqueue
then the directories listed have inappropriate write permissions and
should be secured to avoid various possible security attacks.
+---------------------+
| DIRECTORY STRUCTURE |
+---------------------+
The structure of this directory tree is:
cf Source for Berkeley configuration files. These are
different than what you've seen before. They are a
fairly dramatic rewrite, requiring the new sendmail
(since they use new features).
contrib Some contributed tools to help with sendmail. THESE
ARE NOT SUPPORTED by Berkeley -- contact the original
authors if you have problems. (This directory is not
on the 4.4BSD tape.)
doc Documentation. If you are getting source, read
op.me -- it's long, but worth it.
mail.local The source for the local delivery agent used for 4.4BSD.
THIS IS NOT PART OF SENDMAIL! and may not compile
everywhere, since it depends on some 4.4-isms. Warning:
it does mailbox locking differently than other systems.
mailstats Statistics printing program. It has the pathname of
sendmail.st compiled in, so if you've changed that,
beware. This isn't all that useful.
makemap A program that creates the keyed maps used by the $( ... $)
construct in sendmail. It is primitive but effective.
It takes a very simple input format, so you will probably
expect to preprocess must human-convenient formats
using sed scripts before this program will like them.
But it should be functionally complete.
praliases A program to print the DBM or NEWDB version of the
aliases file.
rmail Source for rmail(8). This is used as a delivery
agent for for UUCP, and could presumably be used by
other non-socket oriented mailers. Older versions of
rmail are probably deficient. RMAIL IS NOT PART OF
SENDMAIL!!! The 4.4BSD source is included for you to
look at or try to port to your system. I know it doesn't
compile on {SunOS, HP-UX, OSF/1, other} (pick one).
smrsh The "sendmail restricted shell", which can be used as
a replacement for /bin/sh in the prog mailer to provide
increased security control. NOT PART OF SENDMAIL!
src Source for the sendmail program itself.
test Some test scripts (currently only for compilation aids).
